CLUTCH-LEVER COLLAR.

Application filed July 18, 1921. Serial No. 485,636.

T 0 all whom it may concern:

Be it known that I, CLARENCE G; WOOD, a citizen of the United States, residing at Muncie, in the county of Delaware and State of Indiana, have invented certain new and useful Improvements in Clutch-Lever Collars, of which the following is a specification.

The invention relates to clutches of the type wherein there is a driving and a driven member, which members are locked together by means of levers pivoted on a clamping p ate and cooperating with a cam surface, and has for its object to provide in connection with such a clutch a clamping lever collar, which collar is provided with spaced flanges, one of said flanges being integrally formed on the main body of the collar and stamped from a single piece of material, and a clamping lever spacer stamped from a single piece of material and encircling the collar, said spacerbeing stamped from a single piece of material and provided with struck-in lugs adapted to be welded or otherwise secured to the flange of theclamping lever collar.

A further object is to provide a clamping lever collar having annularly arranged lever end receiving pockets formed by an integral flange carried by the collar and by a' spacer surrounding said collar and provided with struck-in portions secured to the clamping lever collar.

\Vith the above and other objects in View the invention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawings, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings Figure 1 is a vertical longitudinal sectional view through a lever controlled clutch. showing the clamping lever collar applied thereto.

Figure 2 is a sectional view takenon line 22 of Figure 1.

Figure 3 is a view looking into the clamping lever collar.

. for frictionally Figure 4 is a vertical sectional view taken on line 4-4 ofFig'ure 3.

Figure 5 is a perspective view of the clamping lever spacer.

Referring to the drawings, the numeral 1 designates a driving member having a chamber 52 therein. Extending into the chamber 2 and having, its end rotatably mounted in an anti-frictional bearing 3 is a driven shaft 4, which driven shaft is provided with-a drive plate 5., which drive plate is forced into bmding engagement with the driving member 1 by means of a clamping plate 6 cooperating-with friction discs 7. The driving memberl is provided with an adjusting ring 8 with the bevelled surface 9 with which aplurality of clamping levers 1O cooperate, said clamping levers being pivotall mounted at 11 on the clamping plate 6. d usting ring 8 is carried by a cover 12 detachably secured to the driving member and interposed betweensaid cover and a spacer flange 13 carried by the clamping lever collar 14 isa coiled spring 15, which spring normally forces said collar inwardly holding the driving and driven members together.

The clamping lever collar 14 is stamped from a single piece of material and provided with an integral flange 15 flange 15 and the lever spacer flange 13, the inwardly extending lugs 10 of the clamping levers 10 are disposed. Spacer flange 13 is stamped from a single piece of metal and provided with offset U-shaped members. 16 of uniform depth which are adapted to enbetween which gage the collar flange 15 and be Welded or otherwise secured thereto at 17, preferably welded. It will be seen that by so constructing the collar 14 and its flanges, that the parts are reduced to a minimum and so constructed that they may be stamped from sheet material thereby obviating machining the collar and consequently reducing the cost of the same to aminimum. By providing the U-shaped members 16 stops are provided within the groove of the collar, so as to limit relative transverse movement between the inwardly extending lugs 10 of the clamping levers 10 and the collar. This is of advantage in assembling the clutch parts as it per mits the clamping plate 6, the three levers carried thereby and the clamping lever collar 14c to be assembled previous to placement in the clutch casing, and by turning the collar 14:, the grooves 18 of the clamping plate can be brought intoalignment with the pins 19 carried by the driving member 1 and moved into operative position. When the collar 14 is rotated the U-shaped members 16 engage the lugs 10 of the levers and cause the clamping plate 6 to rotate until the grooves 18 are in position to receive the pins 19, at which time the operator forces the clamping plate 6 inwardly to operative position. flhis permits rapid assembly and a material saving in time. and labor. If so desired the spring 15, plate 12 and bearing ring 8may also be assembled with the other parts, that is collar, levers and clamping plate 6, in which case the plate 12 would not permit the clamping plate 6 and stop pins 19 to beeasily seen. when applying said parts within the casing. It will also be seen that the collar and the spacing flange can be stamped and then welded so that a smooth 'oh and finish is obtainable withoutmachinmg, and without the use of any elements to secure the collar parts together, so that there are no parts or elements to become loose or rattle.

Slidably keyed 'on the driven shaft 4 is a release sleeve 20, the inner end of which extends through the flanged opening 21 of the collar 14 and is in turn provided with an annular flange 22. interposed between the annular flange 22 and the flange 23 of the collar 14 is a thrust bearing 24:, said thrust bearing taking up the thrust and at the same time reducing the friction to a minimum at this particular point. The releasing sleeve is provided with pins 25, which pins engage the outer side of the flange 23 of the collar and prevent inward movement of said sleeve lar adj a cent said annular flange,

when forced inwardly for locking the clutch elements together, and permit play between the sleeve 20 and the collar 14.

llhe invention having been set forth what is claimed as new and useful is 1. The combination with a clutch comprising a driven and a driving element, said driven and driving elements being locked together by means of levers having their arms terminating ad'acent the driven shaft, of a collar surroun ing said driven shaft, said collar bein stamped from a single piece of material an provided with an annular flange, aspacer flange surrounding said colsaid spacer collar being provided with spaced lugs secured to the annular flange of the collar, thereby forming spaced segmentally shaped lever engaging grooves carried by the collar.

2. A clutch lever collar comprising a cylindrical body member having at one of its ends an outwardly extending integral flange, said body member and flange being stamped from a single piece of metal, a spacer flange surrounding the body member, said spacer flange being provided with spacing lugs struck in from the main body of the flange and adapted to be secured to the flange of the body member, said spacer flange and lugs being stamped from a single piece of metal.

3. A clutch lever collar comprising a cylindrical body member having at one of its ends an outwardly extending annular flange, at 1ts other end an inwardly extending annular flange, a spacer flange surrounding thev body member adjacent the outwardly extending annular flange, lugs carried by the spacer flange and secured to the outwardly extending flange of the body member, said body member and spacer flange being stamped from single pieces of material.

In testimony whereof I affix my si nature.
